2008 335i e92 Poor Mpg

I have 2008 335i e92 100% stock, 65000 miles on it, no check engine or any lights in dash for that matter. Always filled up with chevron 91, and have done all maintenance on it. Ever since I bought it I would get 19-21 with aggressive driving. On the other hand driving like a gramma would get me an amazing 23-25 mpg. Now all of a sudden I've been getting 12.5-13.5 mpg combined. I get 205-215 Miles from a full tank of gas. Has anyone experienced this. I would expect this gas mileage with a 2008 m3 but not a 335i. Any help much appreciated before I take it in to BMW to have them take a look at it. Btw I have checked tire pressure on all tires manually (I don't trust TPMS).
Thanks

wow i thought i was the only one im averaging 12.5 as well, and i dont really push my car, i dont track my car, and i only use 93 oct BP or SHELL. I took it to the dealer twice even though they were shocked, but they cant seem to find whats causing this so im getting the every is fine. there was a time when it was as bad as 9 mpg my car is still under warranty so all maintenance are up to date. hopefully ur dealer figure it out. keep me updated will you? btw i a 09 335 xi with 41,000 miles

I'm gonna wait it out 2 weeks or so. If it doesn't get any better by then I will be taken it in to have them take a look at it. I'll keep you updated. Let me know if you fix it before I do.
Thanks

Check your tire pressure? Do you do a lot of city stop and go traffic ?

My tire pressure is right on. I have started to fill at shell, reset my computer and drive speed limit for once. Now im getting 18 mpg which is a great start. Is there such thing as bad gas? I had about two tanks that got me no more than 13 mpg. Ever since I changed from Chevron to Shell I saw a great improvement. Anyway I'll keep you guys updated.
